Food allergy is a type of immune reaction that occurs when the body mistakenly identifies certain foods as harmful. The immune system releases histamine and other chemicals, causing a range of symptoms that can vary from mild to severe.

Symptoms can appear immediately after eating or can take several hours to develop. Recognizing the signs of food allergies is essential to avoid serious complications. Here are some of the common signs of food allergies with pictures.
